ABSTRACT:
A method for preparation of block copolymeric nanoparticles is disclosed. The method is a single-step preparation in which block copolymeric nanoparticles are produced directly from a solution of crosslinkable block copolymer in a carrier medium. The block copolymeric nanoparticles thus formed have at least one crosslinked polymeric phase.
